When you want to find out things like where you’re losing people’s attention or where you should focus visitor engagement, you can use a specific type of heat map called a scroll map. Scroll maps quickly collect data on how visitors scroll through your website, so you can spot UX improvements, make changes, and ultimately increase conversions.

After all, happy users are good for business.

By the end of this post, you’ll know everything you need to know about scroll maps: what they are, how to set one up, and how to use them to find insights that will supercharge your user experience. We cover:

What is a scroll map?

A scroll map is a type of website heat map that visually shows how far users scroll down a page. Scroll maps can be collected on desktop, mobile, and tablet and color is used to represent the most and least viewed parts of a page, from hot (popular) to cold (unpopular).

Scroll maps aren’t just about color: percentages are given to let you know how many users ventured further down the page. An average fold score is also calculated so you can easily visualize the part of the page most visitors see before they start scrolling.

Scroll maps vs. heat maps

scroll map heat map

Heat map (or heatmap) is really an umbrella term for different types of visual website analytics. Scroll maps are one type of heat map, where the ‘hottest’ colors show the most viewed sections of the page, rather than the most clicked (or tapped) elements of it.

In other words, scroll maps generate heat zones of your website or app pages from top to bottom, so they look more like a vertical rainbow instead of depicting the ‘confetti’ patterns typical of other types of heat maps like click or move maps.

5 ways to use scroll maps

You can be as creative as you like when it comes to spotting data patterns and UX optimization opportunities. To help you out, here are five of the most common ways to use scroll maps.

1. Find out where you’re losing visitor attention

Your scroll map will show you how far down the page users reach (the percentage data will help, too): the colder the color, the fewer people will have seen that section of your page.

If your goal is to get users to scroll further (for example, you have a long landing page and want to make sure they see all of the information on it), scroll map data will help you think practically about how you can tweak the design or copy to make that behavior more likely.

2. Spot false bottoms

Sometimes, your visitors don’t realize there’s more content lower down the page. This is known as a ‘false bottom’, and it could be caused by white space, line breaks, or blocks that confuse users. Using a scroll map, you can ‘depth test’ your pages to check for false bottoms.

A quick case study: a scroll heat map on Hotjar’s careers page showed a sharp change in color (from green to blue) toward the bottom of the page. Only 20% of users made it to the end, meaning the 5/5 Glassdoor rating (valuable social proof) was missed by 4 out of 5 visitors. If we want more people to see that element, we need to move it higher up the page!

3. Discover if users see what’s above the fold

The part of a website known as ‘above the fold’ is the bit that the largest majority of people will see upon landing—the ‘fold’ is simply the cut-off point at the bottom of a user’s screen before they need to scroll.

A scroll map automatically calculates the average fold on your page, for both desktop and mobile users (note: these will be very different!). By looking at scroll map average fold data, you can place important elements above the fold in a way that works across devices, to focus user engagement as soon as visitors land on the page.

4. Figure out if users can find what they need

You’d be forgiven for assuming that the goal of optimizing a page using a scroll map is to get as many people as possible to scroll all the way to the bottom. But you’d be wrong. In some cases, users scroll because they can’t find what they need.

Case in point: UK-based digital agency Epiphany improved their client’s e-commerce site by adding filters to category pages after scroll map data showed users having to scroll too much to find what they needed (here’s the full heatmap case study).

Sometimes, with design, less really is more.

5. Learn if your page offers a good cross-device experience

Users might not behave the same way on desktop and mobile. If you’re optimizing a responsive website (one that re-sizes the same page to each device), a scroll heat map will show you where users stop scrolling on mobile and desktop, so you can design a cross-device experience that works for all your users. 

In general, mobile-optimized pages tend to be shorter, but don’t blindly follow best practices: collect your own scroll map data and find out how your visitors are behaving.

Scroll data is there to help you design pixel-perfect user experiences; you can refer to the data to find exactly where you need a CTA to capture users’ attention on desktop and mobile.

How to set up scroll maps with Hotjar

Setting up a new scroll map is easy; if you’re not already a Hotjar customer, grab yourself a free trial now to get started. 

When you create a new heat map in Hotjar, it will automatically generate all three heat map types (click, move and scroll), so there’s no need to do anything special to implement a scroll map.

Once you're logged into the main dashboard, navigate to the Heatmaps section to get started.

1. Select “New Heatmap”

It’s the big green button, you can’t miss it.

2. Name your new heatmap

name new heat map

Choose a descriptive name like Homepage v1 November or Blog post Jan-6 so you can quickly identify it later.

3. Pick the number of pageviews to capture

page views number

You can set up your heatmap to record data from 1,000, 2,000, and 10,000 pageviews depending on the plan you’re on. Your heat map will be visible from the very first pageviews, so you don’t need to wait around for the limit to be reached before taking a look.

4. Select the target page(s)

page targeting

You can place a scroll map on just one specific page, or collect data between multiple ones.

Remember: only a single scroll map will be generated, so if you select multiple pages make sure they have the same basic layout. Multiple page tracking is ideal for sites with a large number of low-traffic pages (e.g., product or category pages).

5. Click “Create Heatmap”
